I'm not positive, but I think I've seen this film many years ago when I was a lot younger. Either way, I enjoyed it and found it fun to watch all the chimpanzees moving around the house doing certain tasks. The story is about a student who requests to become an assistant for a researcher at his home in the middle of nowhere. The researcher is apparently searching for intelligence in primates and already has a well trained one named Link, who seems to be the smartest and oldest of them all. The researcher wants to put Link asleep, but Link has other plans.

This is one of the better killer-animal movies. It's not really violent or scary, but it's enjoyable and interesting and that's what I liked about the film. A young Elisabeth Shue offers a decent performance as the assistant. She also has an excellent nude scene in the movie. The first 40 or so minutes is pretty much just to show how smart the primates are and introduces the characters. It starts to get more interesting once the researcher disappears one night, leaving the assistant alone in the house with all the primates. I found the movie to be a bit predictable, but most 80s films are anyway. I would have given the movie a higher-rating, but it was a little slow in most of the beginning, but other than that I liked it.

A good killer-animal movie about an orang-outang. A bit slow in the beginning, but interesting and entertaining none-the-less. Worth a check.
